Her spokesperson said: "Taylor Swift wrote This Is What You Came For under the pseudonym Nils Sjoberg."

Calvin - who split from Taylor in May - shared a link to a US article about Taylor writing the song and tweeted: "And she sings on a little bit of it too. Amazing lyric writer and she smashed it as usual."

A string of other tweets followed:

Calvin, 32, ended his messages writing:

Taylor, 26, and Calvin dated for 15 months before parting company in late May.

The Shake It Off singer started dating Tom weeks after the break up.
